ROBERT M. DIXON, OF EAST ORANGE, .NEW JERSEY, ASSIGNOR TO THE SAFETY CAR1 HEATING 85 LIGHTING COMPANY, A CORPORATION OF NEW JERSEY.

RADIATOR.

Application filed April 18, 1908. Serial No. 427,893.

To all whom it may concern:

Be it known that I, ROBERT M. DIXON, a citizen of the United States,residing at East Orange, in the county of Essex and State of New Jersey,have invented certain new and useful Improvements in Radiators, of whichthe following is a full, clear, and exact description, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to heating apparatus, and more especially tosteam heating apparatus adapted for use in railway cars or likestructures.

One of the objects of the invention is to provide a radiator of new andimproved construction, such that a greater amount of heating surfacewill be presented to the interior of the car than it has been possibleto obtain in radiators of equal size of this general character, ashitherto constructed.

Another object of the invention is to provide for better distribution ofthe heat within the railway car.

Other objects will be inpart obvious and in part pointed outhereinafter.

The invention accordingly consists 'in the features of construction,combinations of elements and arrangement of parts'which will beexemplified in the construction hereinafter set forth, and the scope ofthe ap plication of which will be indicated in the appended claims.

In the accompanying drawings, wherein is illustrated one of variouspossible embodiments of my invention, Figure 1 is a view showing inperspective thefloor plan of a railway car, provided with a heatingsystem equipped with radiators constructed in accordance with theinvention. Fig. 2 is a view in plan of the improved radiator. Fig. 3 isa horizontal sectional view showing the interior construction of theradiator. Fig. 1 is a view similar to Fig. 3, but showing a differentembodiment of the invention. Fig. 5 is a view in vertical section takensubstantially on line 55 of Fig. 3, and Fig.6 is a similar view taken online 66 of Fig. 4:.

Similar reference characters refer to similar parts throughout theseveral views of the drawings.

Referring now to the drawings, 1 indi Specification of Letters Patent.

cates the floor of a railway car having mounted thereon independentheating systems as at 2 and 3 respectively, each of which is suppliedwith steam from the train pipe 4. The steam is conducted from the trainpipe by risers 5 and thence through conduits 6 to the radiators, whichare located upon either side of the car near the ends thereof. The waterof condensation is returned from the radiators through conduits 7 and isdischarged beneath the floor of the car by means of traps 8.

Inasmuch as the radiators are identical but one thereof need bedescribedin order to impart a clear understanding of the invention. Thisradiator consists of a chambered casing 10, provided at its inner endwith admission and discharge ports 11 and- 12, which are connected withthe conduits 6 and 7 as above described. The dimensions of the interiorof said casing gradually diminish in a direction toward the end of thecar. Communicating with the admission port and leading therefromlongitudinally of the casing is a conduit or passageway 13, the oppositeend of which is open and terminates at a point adjacent the outer end ofthe casing. In Figs. 3 and 5 of the drawings this conduit or passagewayis constituted by a sect-ion of piping of suitable length which isinserted in the admission port 11, the opposite end of which issupported by means of a rod 14 which takes in a recess formed in a plugwhich closes the outer end of the casing. In Figs. 5 and 6 thispassagewayis formed by the upper walls of the casing and a Web 15, whichis cast within the casing and forms an integral part thereof.

In order to provide a fall for the circulating medium the conduits orpassageways are inclined downwardly from the admission ports to thepoints at which they discharge the circulating medium into the interiorof the casing.

In use the steam whichis supplied by the train pipe passes through therisers 5 and conduits 6 into the admission port of the radiator, and isthen conducted by conduit 13 to the opposite end of the interior of thecasing. The water of condensation flows from the casingthrough thedischarge port 12, a suitable fall being provided therefor Within thecar. Moreover,

by reason of the fact that the bottom wall of the casing is inclined ina direction toward the middle portion of the car.

Casing 10, as will be observed, is provided throughout its length withtransversely extending radiating ribs which operate to increase theradiating surface of the radiator. The radiating ribs formed exteriorlyof the bottom wall of the casing gradually decrease in length from theouter end of the casing toward the center of the car, and, inasmuch asthe radiator rests upon the floor of the car, these ribs provide for aproper inclination of the bottom wall of the casing, insuring thedischarge of the water of condensation.

It will accordingly be seen that I have provided a construction welladapted, to attain among others, all ofthe ends and objects aboveenumerated in a simple yet efficient manner.

The radiators, constructed in accordance with the present invent-ion,provide a maximum amount of heating surface with the utilization of aminimum amount of space a greater amount of heat is distributed at theends of the car where'most desired than it has been possible to obtainin heating systems as heretofore provided.

As many changes could be made in the above construction and manyapparently widely different embodiments of this invention could be madewithout departing from the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanying drawingsshall be interpreted as illustrative and not in a limiting sense.

Having described my invention what I claim as new and desire to secureby Letters Patent is:

1. A radiator for railway cars and the like provided with inlet anddischarge ports and formed to provide a passage the bottom of whichslopes downwardly toward the dis charge port with the radiator inhorizontal osltion and heat-radiatin flan es u on lower ends the outersurface of said radiator, said flanges projecting below said bottom toprogressively greater distances whereby the of said flanges lie in asubstantially horizontal plane with the radiator in a horizontalposition.

2; A radiator for railway cars and the like having formed therein inletand discharge ports adjacent the same end thereof and formed to provideconverging upper and lower Walls, and radiating flanges upon saidradiator and projecting therefrom to a progressively greater extent fromthe end adjacent said ports toward the opposite end thereof.

3. A radiating device of the class described comprising a casing havingits admission port connected with a pipe adapted to conduct thereto acirculating heating me dium and its discharge port connected with waterdischarging means near the admission port, the interior walls of saidcasing converging from the admission end toward the opposite endthereof, said casing being provided exteriorly with a plurality of'adiating ribs and having a passageway downwardly inclined relative to ahorizontal plane in the normal position of the casing for conducting thecirculating medium from the admission port to a point near the oppositeend of the casing.

l. A radiating device of the class described, comprising, incombination, an elongated casing havin'g admission and discharge portsdisposed adjacent each other at one end thereof, a passageway downwardlyinclined relative to a horizontal plane in the normal position of thecasing connected with the admission port and extending to a point nearthe opposite end of the casing and transversely extending radiating ribsprovided exteriorly of said casing, the radiating ribs formed upon thebottom wall thereof, gradually increasing in length from the portedendof said casing toward the opposite end thereof, whereby the bottom wallof the casing will be downwardly inclined in a direction toward the saiddischarge port when the radiating de vice rests with its lower ribs upona horizontal surface.

5. A radiator for railway cars and the like having formed therein inletand discharge ports adjacent the same end thereof and formed to provideconverging upper and lower walls, radiating flanges upon said radiatorand projecting therefrom to a progressively greater extent from the endadjacent said ports toward the opposite end thereof, a conduit extendingwithin said radiator from said inlet port to a point adjacent theopposite end, and means adjacent said opposite end to support saidconduit and permit free expansion and contraction thereof.
